Here are the most typical factors for 500 errors:
(1) Bad permissions, Writable by group
Directories and Folders must be -> 755. Exe programs within the cgi-bin directory must be 755. Pictures, press, and written text details like HTML should be 644.
(2) Bad .htaccess, Incorrect command
In the .htaccess file, you may have included lines that are either written poorly or inconsistent. The best way to repair this issue is to comment out the lines in the htaccess.
You can comment out a range of lines in the .htaccess by including # to the starting point. You must preserve an unique duplicate copy of any file before you create changes.
For example, if the .htaccess looks like
DirectoryIndex default.html
AddType application/x-httpd-php5 php
Then try something like this
DirectoryIndex default.html
#AddType application/x-httpd-php5 php
Broken lines and lines that begin with php_flag are the most typical errors. If you cannot decide which range is the issue, then comment out every range.
(3) Exceeding resources, nothing in the Error Log
It is possible your 500 error is occurring due to too many processes which got jampacked in the server queue.
With SSH (shell) accessibility, you can verify different processes operating on your account. Just type following command:
ps faux
Or follow this command(be sure to substitute login name with the real username):
ps faux |grep username
Once you have the procedure ID ("pid"), just type this to destroy the particular procedure (be sure to substitute pid with the real procedure ID):
kill -9 pid
